The University of Massachusetts will move its offices and the UMass Club, to One Beacon Street, from 225 Franklin St. in the Financial District, starting in January 2016, UMass announced Thursday.

The public university system has been in its current location for 10 years, and the lease is up at the end of 2015. When it moves to the new location, for which it has negotiated a 15-year lease, UMass will have the ability for the five UMass campuses to offer classes in downtown Boston. The move is "aimed at serving the growing number of people seeking to advance their education while working in the city's business/government/commercial core," UMass said in a press release.

“The UMass Center on Beacon Hill will allow UMass to expand its mission of service to the Commonwealth and continue its upward trajectory of progress and growth,” said UMass President Robert Caret in a prepared statement. “This effort is the product of thoughtful analysis and significant deliberation. It represents a major step forward for UMass.”

The UMass Building Authority, the University’s capital-projects agency, negotiated the One Beacon Street lease and will have its offices there, too. Of the 100 University of Massachusetts employees expected to be based at One Beacon Street, nearly half – or 49 – would be employees of the UMass president’s office. UMass Club staff members are not University employees, UMass said in its release.

UMass expects to offer a variety of advanced degrees at One Beacon Street, which is located at the corner of Beacon and Tremont streets. UMass will have four classrooms at One Beacon that can accommodate 120 student, UMass said in its release. Modeled after an academic center that UMass will open this September, its Beacon Street location might augment in-person classes with online programming.

Under the terms of the agreement, the university will lease the 31st and 32nd floors of the office building at One Beacon Street, UMass said. The UMass Club, the UMass Building Authority, the UMass Foundation and UMass campus offices will be on the 32nd floor. Caret's office and offices for other UMass agencies will be housed on the 31st floor.
